Have you ever noticed that a swing has a natural frequency, its swings and a very specific rate. What happens if you apply energy at the same frequency, that is you push at the same frequency?
You will discover that you will be able to increase the amplitude with minimal effort. This is called resonance.

Another example is the singing of a wine glass. A glass harp is a great application. Enjoy the theme to Harry Potter
Theory
Using a wine glass and a speaker, I show you the principles behind resonance.

This is an interactive simulation intended to help students get a better feel for mechanical resonance. Using the given masses and spring constants, students can calculate the expected natural frequency of each spring's oscillation. When the outside oscillator matches any of these frequencies, that particular mass will go into a larger resonant oscillation. By Tom Walsh

A simple way to demonstrate residence is have two tuning forks at the same frequency inserted into the soundboxes. If you strike the first one, the second one should start to ring as well.
